hi
i am recently having a weird lagging on my laptop,basically when i brows internet pages with videos in them or when i play games(during playing when loading from hdd the game freezes for seconds and audio lags).i tried almost every thing i could to determine what causing the problem,i updated my graphics card driver,uninstalled some new programs ,did a clean and a fix for registry with ccleaner.nothing solved the problem.i tried to monitor the system with task manager,but i could not see strange prepossess,and cpu and ram load are normal like before.is there a better way for monitoring performance and solve this problem?
info:
laptop:toshiba l755 -cpu:i5- 6 gigs ram-gt 525m-win 7 home sp1-antivirus eset 5 updated.

Disable hardware acceleration in Flash Player

Use Google to find out how: https://www.google.com/#output=search&sclient=psy-ab&q=disable+flash+hardware+acceleration&oq=disable+flash&gs_l=hp.1.2.0l4.1690.10877.0.14233.23.14.5.4.4.0.167.1658.0j14.14.0....0...1c.1.21.psy-ab.uNmjjaNX1ZI&pbx=1&bav=on.2,or.r_qf.&bvm=bv.49478099,d.aWc&fp=884c05b24674b915&biw=1280&bih=846

Used canned air recently to clean out vents of dust? Canned air should be used every six months.

Reviews at Toshiba for model here: http://us.toshiba.com/computers/laptops/satellite/L750/L755-S5258/

Scan your system for malware?

If clean, disable eset temporarily and see how a saved video runs (do not go on internet w/o protection) and see if a/v is interfering with video playback or not.

Latest flash installed? Run java? Unless you need java, I'd uninstall that, due to continuing security concerns. Yesterday, Secunia reported 11 new security vulnerabilities with the latest version available. Anything from Oracle should not be on a system for now.

thanks for the reply,
disabling hardware acceleration did not solve the problem,even saved videos are lagging a little.i did a scan with eset and nothing detected,i would like to install another malware scanner just to be sure,so could you please recommend a free reliable one?
and about java,my problem started 3 weeks ago as i remember before recent java updates,but i see under control pannel /programs :3 versions of java: java7 update 7(64bit)/java 7 update 25 and java 6 update 39.

What do you use Java for?

In reply to: help,win 7 lag

It's been a known source of Grief for a long time now. Most people don't even need it and uninstall it. If you find that you do need it you can always re-install it.

Use this program to remove all versions of java here: http://singularlabs.com/software/javara/

Reboot.

That's step 1.

Download and install Malwarebytes Free: http://www.malwarebytes.org/

You must be careful what you click on when redirected to c|net site after clicking 'Free Download' @ Malwarebytes site. Click only the large green download button and ignore the one nearby that says something about a download installer helper. Avoid that one at all costs. You only want the executable file and nothing else for Malwarebytes.

Sorry, but that is how they choose to do it. Safer alternative is filehippo,com here: http://www.filehippo.com/search?q=malwarebytes

Update Malwarebytes to latest definitions and then run a full scan and report back. Quarantine (do not delete outright) all malware found, just in case a file needed for Windows is found infected. Quarantine allows you to restore that file, deleting removes that file forever. Quarantine isolates the infected file from the rest of your system where it can do no more harm. No need to delete any file placed in quarantine.

That's step two.

Reboot. Let us know how things are.

If the above does not clear the infection see Grif's sticky malware help topic here: http://forums.cnet.com/7726-6132_102-5098912.html

That's step three. Odds are it is java that is the culprit here. Always run only one version (newest version) of java and one version of flash to be safe.

I'd do without java until they get their act together and come into the twenty-first century as far as security exploits go, just like Microsoft had to do it, beginning with Vista.

sfc /scannow
by mchainmchain / July 21, 2013 5:36 PM PDT
In reply to: malwarebite

Actually, news above is good news.

Click Windows start button and enter cmd in 'Search Programs and Files'. Right-click cmd.exe and run as administrator in administrator account.

If done correctly, you should see: C:\Windows\system32>

Now enter sfc /scannow after the >

Line will look like this: C:\Windows\system32>sfc /scannow

Note the space after sfc_/scannow

Press enter and allow Windows to repair and replace any files not in original condition or corrupted. This may take a bit of time, please allow it to finish. Do not attempt to cancel or interrupt the scannow process.

Reboot when finished to set any repaired Windows files to active status.

As for the hard drive, there are a few disk checking programs available at the vendor's sites:

http://www.seagate.com/support/downloads/seatools/
http://www.samsung.com/us/business/components/storage/hdd/software.html
http://storage.toshiba.com/storage-services-support/warranty-support/software-utilities
http://www.pcstats.com/articleview.cfm?articleid=1583&page=7

If your hard drive vendor is different from the above, go to the vendor's site to grab their hard drive testing software.

Caveat: Under no circumstances should you choose to format your drive as all data will then be lost. Do not format your drive!

Used canned air yet? System must be powered down and off when this is done.

Win 7 has a little known reliability montoring program
by mchainmchain / July 22, 2013 7:49 PM PDT
In reply to: ....

To get to it, do the following:

Click the Windows Start button.

In 'Search programs and files', type "reliability" w/o the quotes in administrator account.

At the top there should be Control Panel(1)> view reliability history

Click that and a new window will open. System score should be no lower than a seven or an eight on a bad day (blue graph line at the top of the window).

Let us know what this program reports as failing programs, warnings, etc,., and what your score is.

CCleaner should have made a registry backup when you did your registry changes. You always should have the option to restore that registry backup if needed; especially if you may feel you made a goof somewhere and removed some registry entry you should not have.

Best advice here is to never fool with the registry. That is why one should never run a registry cleaner of any sort, not even CCleaner, which, btw, is regarded as a mild cleaner. Registry cleaners, are, in my opinion, a solution looking for a problem where none exists.

Registry cleaners are nothing more than snake oil. I'd stay away from them now and in the future.

Use of one may have caused the current condition of your system; and not fixed it.

One of the main issues with a registry cleaner is that it will, for example, tell you that a certain registry key is not used (at the moment) and ok you to delete it. What if you need that key later on?

There must be a reason it is there.

Seasoned IT techs never use a registry cleaner of any sort. Instead of that, the most common technique of restoring a system to proper operation is to restore a known good (clean) image back up of the operating system and hard drive for that system. Time is money to them, and they get the job done in the least amount of time and send it out the door.

hdd
by magician369 / July 25, 2013 7:22 PM PDT

i noticed that there is no lag on my external hdd,i installed a game on it,it seems that the lag is only happening on data on my internal hdd.i am not sure yet,i will continue to test..i definitely need a tool to check my internal hdd,if things stay the same,i will think about getting a new internal hdd.
about ccleaner,it always helped me remove some bugs,it is not so dangerous ,since it saves the registry before deleting it,and i already got the fixed registry back before posting,and nothing happened.but i will try not to miss with them again as you suggested...but it is not my problem now.

Cloning your hard drive
by mchainmchain / July 26, 2013 5:40 AM PDT
In reply to: hdd

I'd suggest that before doing any changes to your system.

Canned air? Up to you whether or not you use it, but an inexpensive fix.

"...but it is not my problem now." How's that?

If IT does make changes to the registry, it is specific only to the problems seen, and no other. Backups are always made (image) before attempting such. That is where IT differs from a general registry cleaner. They know better than that. Not only that, but bug reports will be submitted, if needed.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
